Makers' Marks : Physical Markup for Designing and Fabricating Functional Objects

To fabricate functional objects, designers create assemblies combining existing parts (e.g., mechanical hinges, electronic components) with custom-designed geometry (e.g., enclosures). Modeling complex assemblies is outside the reach of the growing number of novice “makers” with access to digital fabrication tools. We aim to allow makers to design and 3D print functional mechanical and electronic assemblies. Based on a formative exploration, we created Makers’ Marks, a system based on physically authoring assemblies with sculpting materials and annotation stickers. Makers physically sculpt the shape of an object and attach stickers to place existing parts or high-level features (such as parting lines). Our tool extracts the 3D pose of these annotations from a scan of the design, then synthesizes the geometry needed to support integrating desired parts using a library of clearance and mounting constraints. The resulting designs can then be easily 3D printed and assembled. Our approach enables easy creation of complex objects such as TUIs, and leverages physical materials for tangible manipulation and understanding scale. We validate our tool through several design examples: a custom game controller, an animated toy figure, a friendly baby monitor, and a hinged box with integrated alarm.

HapticPrint: Designing Feel Aesthetics for 3D Printing

Digital fabrication has enabled massive creativity in hobbyist communities and professional product design. These emerging technologies excel at realizing an arbitrary shape or form; however these objects are often rigid and lack the feel desired by designers. We aim to enable physical haptic design in passive 3D printed objects. This paper identifies two core areas for extending physical design into digital fabrication: designing the external and internal haptic characteristics of an object. We present HapticPrint as a pair of design tools to easily modify the feel of a 3D model. Our external tool maps textures and UI elements onto arbitrary shapes, and our internal tool modifies the internal geometry of models for novel compliance and weight characteristics. We demonstrate the value of HapticPrint with a range of applications that expand the aesthetics of feel, usability, and interactivity in 3D artifacts.

SceneSkim: Searching and Browsing Movies Using Synchronized Captions, Scripts and Plot Summaries

Abstract: "Searching for scenes in movies is a time-consuming but crucial task for film studies scholars, film professionals, and new media artists. Our formative interviews reveal that such users search for a wide variety of entities — actions, props, dialogue phrases, character performances, locations — and they return to particular scenes they have seen in the past. Today, these users find relevant clips by watching the entire movie, scrubbing the video timeline, or navigating with opaque DVD chapter menus. Increasingly, users can also index films through transcripts — however, many interesting characteristics are not contained in the dialogue. We introduce SceneSkim, a tool for searching and browsing movies using synchronized captions, scripts and plot summaries. Our interface integrates information from different documents to allow expressive search at several levels of granularity: Captions provide access to accurate dialogue, scripts describe shot-by-shot actions and settings, and plot summaries contain high-level event descriptions. We propose new algorithms for finding word-level caption to script alignments, parsing text scripts, and aligning plot summaries to scripts. Film studies graduate students evaluating SceneSkim expressed enthusiasm about the usability of the proposed system for their research and teaching."

Cesar Torres

Cesar Torres is a Computer Science & New Media PhD student at UC Berkeley advised by computer-scientist-artist Eric Paulos. His research projects explore digital fabrication technologies as exciting, critical new media. He recently made design tools for enabling data sculpture, dynamic modeling, and haptic design for 3D printing. He also moonlights as a graphic designer and street muralist. He holds a BA in Art Practice and BS in Computer Science from Stanford.
